Temperature Sensor: the temperature sensor in the dishwasher has detected the temperature is too low (below -3 Celsius or above 85 Celsius). This may also appear if the NTC temperature sensor has failed and needs to be replaced.

Water Leak: this code appears when a leak is detected. Drain the base and find the leak to repair it.

Heating System: your dishwasher is not heating or is heating too slowly. This can be caused by a faulty heating element, a faulty temperature sensor, or a faulty connection between the control board and the heater. 

Drainage System Error: this indicates that your dishwasher has failed to drain properly. A blocked or faulty drain hose or pump may be the cause. If this is the case, clean or replace the part. 

Rotor Blocked: this indicates a problem with the wash motor (the part that moves).

Not Filling: this code indicates that water is not entering the dishwasher as expected. The inlet valve that lets water into the dishwasher may need to be replaced or there could be a blockage. If this is not the case, check to make sure that there is not a problem with the water supply to your machine. 

Flow Meter: this code may literally mean you have an issue with your flow meter but it could also be caused by the same issues F6 is caused by. 

Water Level: too much water is detected. This may be caused by a blocked filter, a faulty water inlet, too much laundry detergent in one load, or a faulty spray pump. 

Continuous Water Inlet: this is caused by either a faulty inlet valve that is not closing or there is a short circuit in the main control board. The control board or valve may need to be replaced.

Sensor Failure: this code means that there is a faulty sensor in the dishwasher. 

Optical Water Indicator: this error indicates that there was an error with the sensor in your machine that monitors the water cleanliness. If the washer detects dirty water it may repeat a rinse cycle. If dirt has blocked the sensor, it may also show this code. 

Motorized Diverter Valve: the diverter valve controls the water flow to the upper dishwasher spray arm. If it is faulty it will need checking and possible replacement.

Water Hardness Sensor: water hardness sensors monitor how hard the water is in your area and will let you know if you have to add dishwasher salt to combat hard water. 

Cycle Cancelled or Paused: to fix this issue press the pause/cancel button twice and the power button once. If the problem still persists, unplug the washer and plug it back in after one minute. 

Control Lock Engaged: depending on the model you have you either need to press the control lock button or press and hold it for a few seconds. 

Items Detected in Tub During Clean Washer Cycle: check inside the washer drum for items, remove the items and restart the Clean Washer Cycle

Detergent Cartridge Not Detected: this will only appear of washers with detergent cartridges. If you see this error, make sure the cartridge is in properly. 

Excess Amount of Suds Detected: this message will appear if there is too much suds in the drum. The washer will automatically not drain and continue adding more water and rinse to remove the suds. 

Motor Speed-Sensing Error: this indicates that the motor is not getting to the correct speed required for the cycle. 

Door Not Locked Properly: check to ensure the door is properly shut. 

Low Flow of Water Sensed: check to make sure that both water faucets are turned completely on and check that the hoses are not kinked or plugged. 

Longer Drain Time Detected: when the drain time exceeds 8 minutes, this code will appear. Check to make sure that the drain pipe is not clogged. This may also occur if there is excess suds in the drum.
